Application ined April 1'3. 1906. serainaeiltsa T cir/ZZ 1072/0771, it Wray concern:

Be it known that I, JAMES Hf. MORRISON, a. citizen of the UnitedStates, residingat Day.-A

ton, in the county of Montgomery and State ofI Ohio, have inventeda new and useful.

Lamp-Burner, of which the following a specification.

This invention relates to lamp-burners,

and has for its object to increase the height and Width of Iche flame of.- anordinary burner, andthereby increase its light-p ower. In. this connection it is proposed to employ airfcurrents for increasing the height of the flame and spreading the same andtoproduce these air-currents without making any material alteration in ordinaryor conventional forms` of lamp-burners.

With these and other objects in. view the present invention consists in the combination and arrangement of. parts, as will. bel

hereinafter more fully described, shown in the accompanying drawings, and; particu,-

larly pointed outinv the appended claims, itl

being understood that changes inthe form., proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the` advantages of the invention.

- .In the drawings, Figure l is a perspective view of a lamp-burner embodying thefeatures of the presentinvention, the bell;,or hood being open. Fig. 2 is a longitudinal sectional view thereof withthe bell or hood closed.' Fig. 3 is a topplan view of theburner. Fig. 4 is a detail fragmentary perspective view of a portionl ofthe bell` or hood, ,showing the means for producing one of the `which is fed up and down by means of the usual'spur-wheel (not shown) carriedby a 1 rotatable shaft 5, having the ordinary dislishaped finger-#piece 6.. Snugly embracing the .wick-tube above the body is the usual perforate gallery 7, which is supported'` from the base by means of. arms 8radiating therefrom and; extended. to form. chimney-holding fingers Q, rising` above the topof" the gallery. A conventional. form of.v hood, or bell 10 embraces the upper. projecting portion. of the wick-tube and is hinged to the Agallery or otherwiseremovably connectedthereto. The top of. the hood or bell is provided with the usual. di'ametrie slot 1l., through which the flame rises. The parts thus far described are common and well known, and, therefore may bey varied at will, these parts having been shown in the drawings in order that the application;k and operation of the inventiony may beadequately understood. i For the purpose ofincreasing the height of the flame over'that of an ordinary burner it is proposed to produce upwardly-directed air-currents at opposite sides of the wick- 12, which pierce the gallery andl rise to points draft-'tubes being openat their upper and n lower ends. A convenient form;` of draftbent into substantial U shape in cross-section 'so as to snugly embrace the wicl' tube, to which. it may be soldered or otherwise rigidly connected, said draft-tube beingy set obliquely across the wick-tube, so asto produce a relatively large open lower end and a com,- paratively small open. upper end for the purpose of creating astrongerupdraft than would be produced by a tube of the same diameter throughout its length.

It will be understood that when the lamp is burmngupdraftswill be produced through the passages or draft-tubes 12, the tendency of the drafts being to prevent spreading of the flame and to cause the same to become elongated-or higher than with an ordinary burner. v

In order that the name may also be spread out, it is proposed to provide outwardly-directed currents of air at the saine sides ofthe wick-tube as the upwardly-directed currents of air. To accomplish this feature, the hood or bell 10 is provided upon its inner side, ad-

tube,` and. this. is accomplished by means of;` iipwardly-conve'rged air tubes or passages adjacent the top of the wick-tube, these tube is produced by means of a metallic platev IOO jacent each air-tube 12 of the wick, with an air-tube 13, which ordinarily consists .of a

metal strip connected at opposite ends to the interior walls of the hood, whereby the plate constitutes a chord of the arc of the hood or bell between the ends of the plate, thus producing an upwardly-,directed open-ended air-passage defined between the plate 13 and the adjacent wall portion of the bell or hood. The middle portion of the upper edge of the plate 13 is provided with a pair of substantially V-shaped fingers or projections 14, which extend laterally outward and incline upwardly into engagement with the inner wall ofthe hood or bell, the opening between the projections or flanges constituting an outlet for the air-passage in close proximity to the adjacent lower end of the slot 11 in the bell or hood. At the lower end of the slot 11 there isan outwardly-directed lip or projection 15, bent from the bell or hood and constituting a guide to lead the current of air outwardly. When the burner is lighted, there is an updraft generated in each airtube 13 of the bell or hood, and as these currents escape upwardly and outwardly through the opposite end portions of the slot 11 they will tend to draw or spread out the flame,

which is thereby increased in width, as well as being elongated, by the updrafts through the passages 12.

lt will now be understood that in providing the present improvement no material changes are required in the burner beyond -forming openings 1n the gallery 7 to accom-` modate the draft-tube 12 and in bending out the lips or flanges 15 at the ends of the slot 1 1 in the bell or hood. These additions may be very conveniently made and will not increase thei cost of the burner, while at the same time will materially increase the .light-power. It is also proposed to provide for the double feed of oil through the wick, and this is accomplished by folding the lower end portion of the wick upwardly and passing the same through a loop or clip 16, provided upon the bottom of the body ofthe burner at one side of the open lower end of the wicktube, whereby the wick will be held in two plies and the supply of oil to the upper burning end of the wick will be materially increased. By preference the loop or clip 16 is formed of wire bent into a, substantially L-shaped clip, having its upstanding member soldered or otherwise rigidly secured to the bottom of the base and its under horizontal member or arm lying in substantial parallelism with and at one side of the open lower end of the wick-tube.

In addition to increasing the light the draft-tubes maintain the wick-tube in a relatively cool condition, and the burning of the wick is thereby retarded, which prolongs the life of the wick. Moreover, the top of each tube 13 terminates short of the top of the wick-tube, as experiments have shown that better results are obtained by this relation of partsy particularly as it maintains the wicktube relatively cool, and thereby prevents burning of the tube.

Having thus described the invention, what is claimed is 1. A lamp-burner comprising a wick-tube and a hood, in combination with upwardlydirecting air-tubes arranged at the opposite narrow sides of the wick-tube, and means carried by the hood to direct currents of air upwardly and outwardly to spread the flame.

2. A lamp-burner comprising a wick-tube and a hood, in combination with means arranged to produce an upwardly-directed current of air along the wick-tube at the ends of the flame for increasing the height of the latter, and means carried by the hood to produce currents of air directed to spread the flame.

3. A lamp-burner comprising a wick-tube, a hood having a slot above the upper end-.of the tube for the flame, diverging members extending through the slot at the ends thereof and upwardly-directing air-tubes carried by the wick-tube at the opposite narrow sides thereof for increasing the height of the flame.

4. A-lamp-burner having a wick-tube, a hood provided with a slot forthe outlet of the flame, and means carried by the hood for producing upwardly and outwardly directed currents of air at oppositesides of the wicktube for spreading the flame.

5. A lamp-burner having a wick-tube, a hood provided with a slot for the passage of the fiame, upwardly-directed air-tubes carried by the wick-tube for increasing the height of the flame, 'air-tubes carried by the hood, andmeans associated with the latter tubes for directing currents of air therefrom upwardly-and outwardly to spread the flame.

"6. A lamp-burner having a pair of plates folded into substantial U shape and embracing opposite narrow sides of the wick-tube to form upwardly-directed air-passages which deliver the air-currents to the ends of the flame, each plate being disposed obliquely across the wick-tube to give the air-tube an upward taper.

7. A'lamp-burner having a'Wick-tube, a hood having a slot for the passage of the flame, outwardly-directed and upwardly-inclined lips extending from opposite ends of the slot in the hood, and upwardly-directed air-passages carried by the hood andleading to the respective ends of the slot in the hood.
